UAV No Fly Zone app... now available on iOS Devices.
This app contains over 46,000 airports around the world which can be displayed quickly and easily when flying RC models. When flying RC/UAV's commercially, these areas are considered "No Fly Zones" based on your geographic location.
For example when flying UAV's in Canada, Transport Canada has set a 9km no fly zone around Airports without proper legal authorization.
By default this app sets a 9km radius around Airports and will display all airports within 30km of your marker.
These settings can be adjusted depending on geographic location and rules in your area.
